@bsflower13 We have saved tomato seeds for years but not grape ones. Simply take a really nice tomatoes and slice them about 1/4" thick and lay them on a dehydrator tray to dry. (Don't dehydrate, just use the tray.) It needs air flow under on the underside also. Turn occasionally as it dries. Put them in a ziplock bag or jar and cap. When ready to start, place a dry sliced tomato on soil and lightly cover with soil and water well. Ooooodles of tomato starts!
